Correct answer will be upvoted else downvoted. table can be addressed as a square shape with stature h and width w, isolated into h×w cells. Let (i,j) signify the cell in the I-th line and the j-th segment of the square shape (1≤i≤h; 1≤j≤w). Into every cell of the table you can either put a plate or keep it unfilled. As every visitor must be situated close to their plate, you can just put plates on the edge of the table — into the first or the last line of the square shape, or into the first or the last segment. Officially, for every cell (i,j) you put a plate into, no less than one of the accompanying conditions should be fulfilled: i=1, i=h, j=1, j=w. To make the visitors agreeable, no two plates should be placed into cells that have a typical side or corner. All in all, if cell (i,j) contains a plate, you can't place plates into cells (i−1,j), (i,j−1), (i+1,j), (i,j+1), (i−1,j−1), (i−1,j+1), (i+1,j−1), (i+1,j+1). Put whatever number plates on the table as could be…

0 A ladder tournament L can be split into two separate ladder tournaments L and L byassigning each player either to L or to L. The new ranks of the players are adjustedso that they do not contradict the relative rankings in L. However, there are manyways to define the inverse operation, joining two tournaments of disjoint players.Design algorithm Join-Ladder-Tournaments(L, L) that gives both tournamentsan equal value. This means, for example, that the joining does not force the championof L to compete against the worst players in L before she can have a match withthe champion of L
